Littelfuse, Inc offers the new C&K Switches NanoT product line, a series of miniature, surface-mounted, extremely low profile, waterproof tactile switches.

Smart wearables, health monitoring devices, and other battery-powered IoT devices are driving demand for greater active components integration, seamless rounded screens, and extra functions in ever smaller spaces. The result is a need for the switch interface to be much smaller. The new switch series is the smallest tactile available, providing product designers room to construct extra functionality or reduce their PCB size.

"We are excited to release the NanoT switches, the world's smallest tactile solution currently available for high-end portable, wearable consumer and medical applications," said Daisy Liu, global product manager at C&K Switches, now part of Littelfuse. "They provide the smallest size, IP67 waterproof tact switch available. They use the surface-mount technology reflow process for the top version and Pin-in-Paste reflow process for the side version. As a result, this product addresses the market's demand for smaller components while providing our customers with the ability to deliver high quality and high performance in their latest designs."

The ultra-compact size enables designers to add functionality or reduce PCB size, delivering significant space-saving over other solutions on the market. The side-actuated package measures just 2.2mm x 1.7mm x 1.65mm, saving 35%, and the top-actuated package is 2.1mm x 1.65mm x 0.55mm, saving 20%.

The device is perfect for wearable and portable consumer electronics, such as hearing aids, headsets, and portable IoT devices.
